Abstract

The present application provides a reusable ultrasonic surgical instrument, comprising a sleeve assembly, a knife rod, a base and a clamping drive assembly, the sleeve assembly includes a clamp, an outer sleeve and an inner sleeve arranged at the distal end, Both the outer sleeve and the inner sleeve are arranged coaxially with the cutter bar; two rotating shafts are arranged at the proximal end of the clamp, and one of the two rotating shafts rotates with the outer sleeve Connected, another rotating shaft is rotationally connected with the inner sleeve; the sleeve assembly can be disassembled from the base and the clamping drive assembly toward the distal end of the knife rod axis or toward the knife rod The proximal direction of the axis is installed on the base and the clamping drive assembly; the outer sleeve is connected to the base through one or more first detachable structures; the inner sleeve is connected to the base through one or more A second detachable structure is connected with the clamping drive assembly. The application has the advantages of simple structure and low cost.

Description

technical field [0001] The present application relates to a surgical instrument, in particular to a reusable ultrasonic surgical instrument. Background technique [0002] With the popularization of minimally invasive surgery, ultrasonic scalpel has become a routine surgical instrument. The ultrasonic knife uses an ultrasonic frequency generator to mechanically vibrate the knife head at a certain ultrasonic frequency, so that the water molecules in the tissue are vaporized, the hydrogen bonds of the protein are broken, and the cells are disintegrated, so that the tissue is cut or coagulated, and the blood vessel can also be closed. . The ultrasonic scalpel enables tissue cutting and coagulation to stop bleeding at the same time, and has less lateral thermal damage. [0003] The ultrasonic scalpel system is mainly composed of ultrasonic frequency generators, transducers and surgical instruments. Among them, the ultrasonic frequency generator sends out oscillating electrical...
